Why is there a difference between larger and smaller grain sizes in terms of the effect of velocity needed to keep particles in suspension? Group of answer choices Smaller particles like to hide out along the bed of the stream. Larger grain sizes like gravel bounce to the top of a stream and then drop straight down again. Larger grain sizes have their own momentum that keeps the afloat, Larger grain sizes are harder to suspend, because they have higher fall velocities. Very small grain sizes are easy to suspend, because they have very small fall velocities
